Probably the most-beloved symbol of Viennese arts, and one of the first buildings to be rebuilt in the postwar era. It was built from 1861-1869 under the direction of architects Eduard van der Nüll and August von Siccardsburg for then-emperor Franz Josef I. The first performance was Don Giovanni, an opera by Austrian native Mozart, on 25 May 1869. The architecture of the opera was barely tolerated by the picky Viennese when it opened. Van der Nüll did not take these criticisms of his work lightly and committed suicide. A few weeks later, von Siccardsburg died of a heart attack. Doubly cursed, the opera building succumbed to bombs less than 100 years later, during World War II. After ten years of Allied control after the end of the war, many cultural institutions reopened to celebrate the birth of the new Austrian state. This time the opera opened with an adopted son of Vienna's work: Beethoven's Fidelio. The lush curtains and overall elegance contribute to the atmosphere (even the nosebleed seats, so steeply pitched and close to the ceiling a nosebleed becomes a distinct possibility). Inexpensive standing room tickets are made available for every performance and sold the day of the performance. The line forms about two hours prior to the performance. Guided tours in a number of languages are offered. The line at the front side door forms about 1/2 hour before the tour.
The Vienna State Opera is an opera house and opera company located in Vienna, Austria. The 1,709-seat Renaissance Revival venue was the first major building on the Vienna Ring Road. It was built from 1861 to 1869 following plans by August Sicard von Sicardsburg and Eduard van der Nüll, and designs by Josef Hlávka. The opera house was inaugurated as the "Vienna Court Opera" in the presence of Emperor Franz Joseph I and Empress Elisabeth of Austria. It became known by its current name after the establishment of the First Austrian Republic in 1921. The Vienna State Opera is the successor of the old Vienna Court Opera. The new site was chosen and the construction paid by Emperor Franz Joseph in 1861.

Once a palace, it is now the most popular exhibition space in Vienna, mainly for traditional modern art. The building itself is an experience as well. It is home to a valuable drawing collection, including many works of the German Renaissance painter, Dürer.
Casino Wien
The casino is at Palais Esterhàzy, on the famous Kärtner Strasse near the Opera and is operated by state-owned Casinos Austria. In addition there are several poker casinos (e.g. Montesino) and many, many tiny slot-machine and betting places. The latter often occur in groups of three (because there is a legal limit on the number of slot machines per venue). They do not offer any glamor or flair and are best avoided by tourists.
